-Batman: Year 100 is a actually the 3rd custom I've done - and I'm quite happy with it. It started off as a Batman: Dark Victory figure, whose ear got damaged. In doing a reread of the trade, I was inspired, and went to it. I shaved down both ears, so they were both consistent, and then took some out of the middle of the cape, in order that it match the split in the book. I repainted the belt and the body then, to better match the color in the book. I sketched out the bat-symbol on the body itself, in pencil, and then proceeded to paint that in as well. I used a black, ball-point pen to make the sweater-effect on his arms, as the shirt Batman wore in the book was a sweater. I attached an assortment of weapons - including two pieces of equipment from a Star Trek: First Contact Borg figure, a lego-computer, and a mini-gun, that looked an awful lot like a wielding tool, or laser to cut through something.
-I fashioned a few, rudimentary bat-a-rangs out of thin cardboard. I had an official bat-a-rang from a previous Batman figure, but it seemed out of place with the way both the comic presents the character, and inconsistent with the tone I was going for - so I whipped a few up myself.
-That said - I intentionally went with a bit of a rag-tag look to the figure. I appreciated how, in the Year 100 world, Batman didn't have the fortune or the tools of his main stream counterpart. I tried to represent that in how I attached parts, made the bat-a-rangs, painted the symbol, etc. I actually had more precise lines, and a few cleaner cut areas - but did a few repaints in order that the tone be a more accurate to the character.
